Getting Started

First 8-weeks

Once you have been selected to participate in EBB you have eight weeks to hire a contractor or decide do the work yourself as an owner-builder, and get a building permit. EBB does not require a homeowner to use a contractor or recommend any specific contractor to complete the retrofit work. If you would like to hire a Contractor please review following information "What You Should Know Before Hiring a Contractor".

You may choose from the Contractor Directory or select another company not listed. The Directory provides a resource to search for licensed contractors who are educated in seismic retrofitting in your area. If you choose a contractor from the Directory you may authorize them to upload required documents on your behalf. You can do this from your online Homeowner Dashboard. 

If you choose to use a contractor, the CSLB website has information on consumer resources including how to select a licensed and qualified contractorchecking a contractor licensenegotiating contracts for work to be done, preventing and resolving disputes, and how to obtain a building permit.

If you choose to do the work yourself, you will identify yourself as an owner-builder. As an owner-builder, you become the general contractor for your project and assume complete responsibility for the overall job, including state and federal taxes, workers' compensation insurance and other legal liabilities. You will be installing bolts into the foundation and plywood or oriented strand board (OSB) bracing along the stud wall (cripple wall) of your crawl space. DIYers are encouraged to view the education videos, which details the steps for installation of retrofit components.
